The flow sensor is one of the most important components of your anesthesia device, as it ensures proper ventilation during a procedure. It automatically checks patient airway flow 250 times per second, making it the "eye" of your anesthesia system. When the flow sensor isn’t changed on schedule or maintained properly, it can lead to failed checkouts which may delay case start times.Compatible with the following GE Healthcare equipment:Aestiva,Aespire,Aisys (CS2),Avance (CS2)
